14.Servicing - The user should not attempt to service the appliance
beyond that described in the operating instructions. All other
servicing should be referred to qualified service personnel.

Precautions:

1. Power – WARNING: BEFORE TURNING ON THE POWER FOR THE
FIRST TIME, READ THE FOLLOWING SECTION CAREFULLY.
All models are designed for use with either AC120V, 60Hz or
AC240, 50Hz voltages. The unit will autoswitch to either of these
voltages.

2.

Do Not Touch The A-H1 With Wet Hands – Do not handle the
AH-1 or power cord when your hands are wet or damp. If water
or any other liquid enters the A-H1 cabinet, take the A-H1 to a
qualified service per

son for inspection.

3.

Car

e – Fr

om time to time you should wipe off the fr

ont and side
panels of the cabinet with a soft cloth. Do not use rough materi­al, thinners, alcohol or other chemical solvents or cloths since
this may damage the finish or remove the panel lettering.

SAFETY INSTRUCTIONS

NEVER connect the Link Out to another Link
Out or A-BUS Ready output. This may dam­age the components and void the warranty.

INSTRUCTIONS FOR CONNECTING AND USING RUSSOUND MODEL A-H4. REFER TO THE DIAGRAMS INSIDE.

A-H4 OVERVIEW

The A-H4 is an

A-BUS 4-zone, 1-source Audio Distribution Hub
used with A-BUS Amplified Modules. The A-H4 can also be linked
to other A-BUS Hubs (such as the A-H484) and to A-BUS Ready
stereo receivers in order to increase the number of zones in a
system.

IMPORTANT – Before installation, review the manuals included
with each component in your system. If you are unsure of any of
the installation procedures described herein or elsewhere, consult a
professional electronics installer.

A-H4 KEY FEATURES

1) 1 source audio input and loop output

2) 4 common IR outputs, with confirmation LED

3) Status power input with LED indicator and selector switch

4) Power input with LED indicator

5) Link In and Out

6) Compact size for mounting near audio equipment

Although the A-H4 has only 1 audio input, it can be connected to
multiple audio sources via the Tape 2 or Zone 2 output of a stereo or
home theater receiver. Connecting to a receiver gives the A-H4 access
to any audio source connected to that receiver. If a single audio
source is connected directly, it can be shared with the receiver by
using the Audio Out on the A-H4.

A-KP2 keypads can be operated manually or by using the optional
A-KP RC remote control. A-VC2 volume controls are operated manu­ally using the rotary knob. If you installed IR emitters (see Step 2),
then sources can be operated with their own remote control by aim­ing it at the IR window on an A-KP2 keypad.

Mount the A-H4 near the source equipment using screws or hook and
loop fastener.

The Link In and Out is used to connect the A-H4 Hub with an RJ45
patch cable to other A-BUS single-source Hubs or an A-BUS Ready
product to increase the number of rooms in a system. The Link con­nects the Common IR, Status, and the audio source signal. Single­source A-BUS Hubs such as A-H4, A-H2, A-H4P and A-H1 all use the
same format for linking. The A-H484 multi-source Hub is different
and cannot be linked to single-source Hubs in this manner.

The Link Out or A-BUS Ready Sub-Zone output of one device must
be connected to the Link In (Expansion Input of A-H2) of the sub­sequent device.
NEVER connect the Link Out to another Link Out or A-BUS Ready
output. This may damage the components and void the warranty.

Note: Each Hub in the chain requires its own A-PS power supply.

Common IR Outputs. Connect an IR emitter such as the 845.1 to
each of the 4 IR connectors on the A-H4 (you need use only one IR
emitter if you’ve connected a single source directly to the A-H4).
The IR signal that is received through a zone’s Amplified Module is
routed to the A-H4’s Common IR outputs. This allows remote oper­ation of sources such as CD, DVD or DSS from each zone.

5 SOURCE

The A-H4 Hub and Amplified Modules are powered by the
A-PS 24 VDC/2.5A power supply. The A-PS should be plugged into an
unswitched AC outlet (one that is live all the time). When the A-PS
is providing power, the A-H4’s POWER LED will illuminate.

A-BUS®SYSTEM OVERVIEW

The product you have just purchased is an integral part of the Russound

®

A-BUS Multi-Room Audio System. It is a component which, when combined
with other essential components and your source equipment (receiver, CD play­er, etc.), creates a versatile whole-house audio system that will fill your rooms
with high-quality sound for years to come.

A-BUS technology is a new, innovative method of providing high quality audio
to remote locations with a single 8-conductor cable such as CAT-5.
A-BUS technology provides many advantages over other methods of audio dis­tribution, including: simple, single CAT-5 wiring scheme; infrared control of sys­tem components; infrared control of the optional A-KP2 amplified keypad
module; and system power status.

Every A-BUS System is comprised of components from each of the following
three areas.

1.

A-BUS Amplified Modules: The Module contains both the amplifier for the
room’s speakers as well as the control for those speakers. One Module
should be used for each room you choose to control. The Russound A-KP2
Amplified Keypad (with built-in IR receiver) and A-VC2 Amplified Volume
Control are examples of A-BUS

®

Amplified Modules.

2. A-BUS Hubs: All components of the A-BUS system must be wired centrally
to a Hub located near your source equipment. The Hub provides the con­nection for source equipment, volume controls, infrared emitters and power
supply. The A-H484, A-H4, A-H4D, and A-H2 are examples of
A-BUS

®

Hubs. The A-H484, A-H4, and A-H2 are surface-mount units.

The A-H4D is an in-wall Decora®style unit.

3. Power Supply: The power supply plugs into the Hub. The Russound A-PS
24VDC/2.5A unit is an example.

Connect two (4) A-BUS Amplified Modules. A CAT-5 cable is used
to connect each A-KP2 or A-VC2 Amplified Module to a keypad
output on the A-H4 Hub. For clean installations, use RJ45 CAT-5
patch cables to connect from the Hub to an RJ45 Wall Plate
(optional), and then wire from the Wall Plate to the Amplified
Module (see diagram). The Amplified Modules have 110 punchdown
connectors for the 8 individual conductors of the CAT-5 cable (use
a punchdown tool with a 110 blade to insert conductors).

NOTE: When wiring directly to an Amplified Module (i.e., not using
an RJ45 Wall Plate) use T568A RJ45 wire configuration.

1 AMPLIFIED MODULES

The status feature provides two functions:

- Visually confirms when the source component is on

- When the source component is turned off, all Amplified Modules
will also turn off

The status feature requires that the source component has a
switched AC outlet.

To enable the status feature:

- Move the status jumper on all Amplified Modules to the
“Enabled” position.

- Move the status switch on the Hub to the “STATUS” position.

- Using a Russound Model 846C 120V/12VDC or comparable
adapter, connect the coaxial plug end to the STATUS input on
the Hub, and plug the adapter into a switched AC outlet on the
source component.

When the source is on and supplying status voltage to the Hub, the
Amplified Module’s LED indicator will illuminate green. When the
source is turned off, all Amplified Modules that are on will also
turn off (the A-VC will mute).

IMPORTANT: When the status feature is enabled, it must be used
(i.e., supplied with power) in order to ensure proper operation with
accessories such as the A-LC2 Local Sour

ce Input Module.
